Use the ism_watch command to monitor backups and restores sent to the ISM server. During a backup, the ISM server automatically routes storage-space data to volumes in the ISMData volume pool and logical-log files to volumes in the ISMLogs volume pool.
Always keep the volumes from the ISMLogs pool mounted to ensure that a storage device is always available to accept logical-log data. If the volume is not mounted, the backup will pause. For more information on using devices and ISM commands, see the IBM Informix: Storage Manager Administrator's Guide.
During the backup operation, ISM creates save sets of the backed up data and enters information about the backed up data in the ISM catalog. You also can use this command to back up the ISM catalog:
ism_catalog -create_bootstrap
If you use the onbar script to back up storage spaces and logical logs, it backs up the ISM catalog automatically. If you call onbar_d directly, you must use the ism_catalog -create_bootstrap command.
